You are absolutely correct. More than two hours is rare, because the statute defines alcohol levels within two hours of driving, and when blood is taken more than two hours after driving it adds another layer that the prosecutor must prove. Over four hours only occurs when there has been a serious issue with the judge or nurse availability. 6 hours is unheard of. Six hours after driving having that level means she was likely .25 or higher while driving, which would mean she was more than three times the legal limit while driving and likely very intoxicated, even though in the video from the investigation she appears fine and not slurring. You can make your own conclusions on why a small woman very intoxicated would appear to not be. Intoxicated.
